Exploring self-reported helping, punishment, and moral courage within and across group boundaries: Implications for the Inclusion of Others in Self scale

Altruism may not be a unitary concept but may include behaviorally dissociable subfactors. Here, we examined the effects of social distance within and across group boundaries on three facets of altruism: help giving, peer punishment, and moral courage. Using real-life scenarios presented as vignettes, participants were asked to indicate the likelihood that they would engage in the described behaviors across three different social settings: a familiar low-distance in-group, an unfamiliar high-distance in-group, and a hostile out-group. We used the Inclusion of Others in Self (IOS) scale to measure perceived closeness to members of the described social group. We hypothesized that help giving would be most and moral courage least sensitive to variations in social distance. In both studies, results revealed no significant differences in help giving across variations in social distance but a higher self-reported likeliness to show morally courageous acts in the familiar and close in-group compared to the other groups. The results for peer punishment were only partially consistent, following a similar pattern to moral courage. IOS scores discriminated between high and low-distance in-groups, as expected, but did not discriminate well between a high-distance in-group and hostile out-group. On the other hand, facet-specific trait scores correlated significantly with vignette responses. When the three facets were considered together across all vignettes, in-group favoritism became apparent. The studies contribute to our understanding of the social context conditions of altruistic behaviors and call for the refinement of experimental and self-report measures in the study of altruistic behavior.
